Bio Body's most popular 40-Day programme option — a well-rounded starting point that suits most people well. The Protocol option is straightforward to follow and includes complete daily coaching support throughout the full 40-Day structured eating phase. A good choice for those new to Bio Body, returning after a break, or those who are generally active and find structured programmes respond well for them. The extended 40-Day format gives more time to embed the programme tools and build consistency before transitioning to a maintenance approach.
